TO C HATTANOOGA IMPLEMENT AND MANUFACTURING COMPANY,

OF EAST CHATTANOOGA, TENNESSEE.

BALlNG-PRESS.

To all whom, it TII/II/Z/ concern:

Be it known that I, HILLYARD A. STARR, a citizen of the United States, residing at East Chattanooga, in the county of Hamilton and State of Tennessee, have invented a new and useful Baling-Press, of which the following is a specification.

This invention relates to a novel balingpress, and has for its primary object to produce a simple, durable, 'eflicient, and inexpensive all-metal press the plunger and power mechanism of which may be constructed of cast members so combined as to eliminate the necessity for machined bearings or joints.

Another object is to so construct the power mechanism that a compound leverage will be secured to enable bales averaging a hundred pounds to be produced by the application of a single horse-power ofmotive force.

Another object is to provide for the positive retraction of the plunger without the aid of springs or other reactive mechanism and with suflicient promptness to give ample time for the feeding of material to the press without interrupting the movement of the sweep.

A still further object of the invention is to provide the power mechanism with chilled self-oiling bearings.

Another object is to improve the construction of the plunger and the manner of its connection with the plunger-rod or pitman to facilitate the connectionand disconnection of these elements; and a still further object subordinate to those enumerated is to improve the construction and mounting of the tucker or folder.

Still otli er objects of the invention will appear as the succeeding description of the illustrated embodiment of the invention is developed.

In the accompanying drawings, Figure 1 is a side elevation of the press and its power mechanism. Fig. 2 is a plan view, on a somewhat enlarged scale, of the subject-matter of Fig. 1, certain of the parts being broken away. F ig. 3 is a longitudinal section on the line 3 3 of Fig. 2. Fig. 4 is an enlarged sec tion on the line 4 4 of Fig. 2. Fig. 5 is a perspective view of the power mechanism with parts in the positions they assume at the be- Specification of Letters Patent.

ginning of the plunger-stroke Fig. 6 is a similar view with the parts in the positions they assume when the plunger-stroke is nearing completion. Fig. 7 is a sectional plan view with the parts positioned as shown in Fig. 6, the sweep-head being indicated in dotted lines. Fig. 8 is an enlarged section on the line 8 8' of Fig. 1. Fig. 9 is a detail perspective view of the base member of the power mechanism. Fig. 10 is a similar view Fig. 11. is a detail view of the capplate, and Fig. 12 is a detail sectional view showing the connection between the plunger and the pitman.

The entire press structure is portably mounted upon front and rear wheels 1 and 2, which rotate loosely at the outer ends of front and rear axles 3 and 4, located below the power mechanism and the press-box, respectively, as shown in Fig. 3. To the front axle 3 is secured a bolster 5, having the form of a cast plate, as shown in Fig. 10, provided at the opposite ends of its front edge with eyes 6 for the reception of the bolts 7, which serve to connect the hounds 8 of the tongue secured to the axle 3 by U-shaped clips 10, which also serve as securing means for a pair of keepers 11, rigidly retained upon the bolster adjacent to its opposite-end and provided with arouate flanges 12, which overhang the peripheral base flange 13 of the base-plate or supportingcasting 14 of the power mechanism.

In addition to its function as the main supa porting member of the power mechanism the plate 1.4 constitutes a fifth-wheel, since the axle is designed to swing from an axis concentric with the flange 13, upon which the 0 keepers 11 slide. This pivotal connection between the main casting 14 and the bolster is effected by forming the bolster 5 with a chilled stud 15, preferably tapered, as shown,

and extended into a corresponding socket 16,

formed in the plate or casting 14. (See Fig. 3.)

In rear of the substantially circular front portion of the plate 14, the upper surface of which is elevated above the flange 13, is formed a reachsocket 17, comprising a pair of upper segments 18 and 19, spaced apart, as shown in Fig. 9, and an intermediate lower segment 20. In this socket is passed the front end of the tubular reach 21, which is sethe casting 14 is formed with a longitudinallydisposed vertical flange 23, to the rear end of -which is bolted the stay-rod bracket 24,

which facilitates the connection of the stayrod to the main casting. The rear end of the stay-rod 25 is connected by a strap 26 to the press-box 27, the front end of which. is bolted or otherwise secured to the reach-casting 23, (see Fig. 3,) formed with areaoh-socket 29, into which the rear end of the reach 21 is extended and keyed, as shown. Above the press-box 27 is mounted, as usual, a hopper 30, bolted at its rear edge to a pair of lugs 31, located at the opposite ends of a hollow transverse frame-bar 32, extended across the pressbox immediately in rear of the hopper and provided with cars 33 for the attachment of a pair of hook-bolts 34, disposed vertically at opposite sides of the press-box and hooked under the rear axle 4 to retain the latter in place.

The construction thus far described constitutes the framing or supporting structure of the press, and I shall now proceed to describe the power mechanism and the arrangement of the plunger operated thereby to press the material fed into the press-box from the hopper 30.

At a point eccentric to the socket 16 the main casting 14 is provided with an integral chilled stud 35 of tapered form, at the axis of which is retained an oil-tube 36, extended above the stud and externally threaded for the reception of a nut 37. The oil-tube 36 is preferably rigidly secured to the stud-as, for instance, by utilizing the tube as a core, around which the stud is cast in the manufacture of the plate 14. The tube 36 is'designed to contain oil and waste and is in communication with an oil-duct 38, leading to the exterior of the stud adjacent to its upper end and designed to furnish a constant supply of oil to the bearing, of which the stud constitutes one member. The stud 35 constitutes a bearing for a plunger operating or driving arm 39,

having at one end a hub 40, which encircles the stud 35, and is provided at the side thereof opposite the arm with a toothed segment 41, meshing with a segmental toothed retractor 42 of somewhat greater radius than the toothed segment of the arm 39.

The segmental retractor 42 oscillates upon a tapered chilled stud 43, similar to the stud 35 and integral with the outer end of an arm 44, constituting a lateral extension of the main casting 14, as shown in Fig. 9. The stud 43, like the stud 35, is provided with an oil-tube 45, designed to constantly supply oil to the bearing of the retractor 42. The plunger operating arm 39 and the retractor 42 are retained upon their studs 35 and 43 by what may be termed a capplate 46, apertured for the reception of the upper ends of arm 39 and the retractor 42.

the studs and also provided with a considerably larger aperture 47 for the reception of the upper end of a tapered sweep-socket 43, integral with and extended vertically from the plate 14 at a point in rear of the stud 35. (See'Fig. 4.) The cap-plate 46 isretained in place by the nut 37, screwed upon the oiltube 36, and is further secured by a bolt 49, passed through a bolt-flange 50, formed on the cap-plate, and passed through a boltflange 51,integral with the socket 4S and the flange 23 of the main casting. (See Figs. 4 and 9.) The bore 52 of the socket member 48 is downwardly tapered and extends entirely through the member, as shown in Fig. 4. Into this tapered bore extends a similarlytapered b earing member or stud 53, depending from and integral with the sweep 54, designed to rotate with the member 53 as an axis for the purpose of presenting the sweeprollers 55 and. 56, located at the opposite ends of the sweep, to the roller-flanges 57 and 58, formed respectively, on the plunger-operating (See Fig. 6.)

Extended entirely through the sweep and its bearing member 53 at the axis of the latter is an oil-tube 59, communicating with the upper end of the bearing through a duct 60 and having its lower end closed by a plug 61, retained in place by a keeper 62, which latter also serves to prevent the rising of the bearing member 53 in its socket.

Since, as heretofore stat-ed, one of the primary objects of the invention is to avoid machine-work. in. the manufacture and fitting of the various elements of the power mechanism, the usual method of drilling openings in the sweep and fitting stud-shafts therein for the rollers is not followed. On the contrary, the rollers are interposed between the under side of the sweep and angular drop-flanges 63, which constitute bottom bearings for the rollers. Each roller is mounted on a short shaft 64, extending through the sweep and the flange 63 and held from dropping out by a key 65. By means of this construction the shaft-openings instead of being machined are formed by cores in the casting of the sweep, the provision of both upper and lower bearings for the rollers causing the latter to run true and eliminating tortuous strains on the roller-shaft.

The connection between the plunger-operating arm 39 and the tubular plunger-pitman 66 includes a bifurcated connecting member 67, having a shank 63, secured within the front end of the pitman. The member 67 is made to span a lug 69, projecting rearwardly from the arm 39 at a point somewhat removed from its outer end and pivotally connected to the member by a pin 70. (See Figs. 3 and 7.) The opposite end of the pitman 66 is connected to the roller-supported plunger 71 by a connecting member 72, similar to the connecting member 68, except that instead of being bifurcated it is provided with upper and lower cylindrical lugs 73 and '74, extended through horizontal plates 75 and 76, secured between the side walls 7 '7 of the plunger. As shown in Fig. 12, the plate 75 is provided with an opening 78 for the lug 74, while the upper plate is provided with a slot 79 for the lug 73. By this construction a pivotal connection is effected between the pitman and the plunger and said elements are made readily detachable by reason of the fact that the pitman may be swung for the purpose of moving the lug 73 laterally until it is withdrawn from the slot, when, as will be obvious, the pitman and plunger may be readily disconnected.

To prevent lateral movement of the plunger during its stroke, it is provided with a pair of spring-plates 78*, extending forwardly from the side walls 77 and bearing against the side walls of the press-box 27. (See Fig. 8.) The plates 78 are held apart by a strut 79 constituting a brace for the spring-plates and also serving as a rest for the plunger when the latter is withdrawn from the baling-chamber, since, as will be seen by reference to Fig. 8, the strut 79" is disposed in a plane immediately above the socket 29 of the reach-casting 28, upon which it is adapted to rest.

The hollow frame-bar 32 in addition to its function as a rigid part of the frame struc ture of the press also constitutes a housing for a tucker or folder 80, having the form of a plate pivoted at its upper edge within the bar 32 and yieldingly urged by a spring 81 to the position shown in Fig. 3. Thebar 32 serves to protect the folder 80 in a manner to effectually prevent the breaking or; clogging thereof, and the arrangement of the folder positively prevents the plunger-head from becoming stuck in the usual manner.

Power is applied to the head 54 by means of a sweep 82, bolted to the head, as shown in Fig. 2, and braced by a sweep-brace 83 and an equalizing-brace 84, the former being extended through an eye 85, cast at one extremity of the head, as shown in Fig. 2. To prevent sagging of the arm 39 and the outer end of the pitman connected thereto, said arm is provided with a shoe 39 disposed to travel upon a raised arcuate track 39 on the main casting 14, as shown in Fig. 6.

Briefly, the operation of the press is as fol- .ows: Assuming the parts to be in the posi- ;ions shown in Figs. 2, 3, and 5 and the press- )ox to be supplied with a charge of hay, the fotation of the head 54 will present one of its 'ollers to theroller-fiange 57 of the plunger- )perating arm 39. As the head continues to 'otate the arm 39 is forced to swing, carryng with it the pitman and the plunger. The LIHI 39 and the pitman constitute a toggle oward the joint of which the roller of the lead advances during. the inward movement of the parts. As the movement continues, however, the roller reaches the joint and passes on beyond the same, this shifting of the point of application of the power serving to greatly increase the leverage exerted by the power mechanism to compensate for the increasing resistance opposed to the inward movement of the plunger by the material in the press-box. The parts will finally assume the positions shown in Fig. 7, and slight con-" tinued movement will cause one of the rollers on the head to move out of engagement with the arm 39, and immediately after this release is effected the other roller will come in contact with the roller-flange 58 on the retractor 42. The retractorwill now be swung on its pivot in an obvious manner, and as it is geared to the hub of the plunger-operating arm 39 the latter will be swung back to its normal position, where it will subsequently be engaged by that roller which has just operated the retractor, and a repetition of the described operation. will take place. It is to be noted that two plunger-strokes are effected for each complete rotation of the head, since it will be obvious that each of the rollers first operates the retractor to position the plunger-operating arm and then swings the arm to operate the plunger, a repetition of these operations being thereafter effected by the other roller as soon as the first-named roller has moved away from the arm 39. It is also to be noted that by reason of the comparatively great radius of the retractor 42 relative to the radius of the toothed segment 41 the retraction of the plunger will be effect-- ed with greatpromptness, thus giving the operator ample time for the feeding of the press.

It is thought that from the foregoing the construction, advantages of my baling-press will be clearly comprehended; but while the present em bodiment of the invention is thought at this time to be preferable I desire to expressly reserve the right to effect such changes,
